Just a brief note on the subject of variety when creating caches. One of the advantages in planning a series of caches is the environment in which the cache owner takes you making the walk enjoyable as well as making the effort involved appear less arduous. Add to that the variety of caches created such as a hollowed out log, a magnetised bolt, or a synthetic rock....etc, as opposed to bog-standard containerised caches, you then have a more enhanced experience testing not only navigational skills but keen observation.
I've just completed a series entitled "Farms" created by Ottaway's123, in West Sussex, UK. The CO in this case employed all of the above providing a very pleasant walk but not one guaranteed to easily pick up all the caches in the series. He/she is to be commended for their ingenuity, and hard work! TFTCs, snake0073.
